T 0 all whom it may concern:

Be it known that I, EUGENE A. IVIDMANN, a citizen of the United States,and resident of the borough of Brooklyn, county of Kings, city and Stateof New York, have mvented certain new and useful Improvements inTalking-Machine Needles or Styli, of which the following is aspecification.

My invention relates to a talking machine stylus and has for its objectto provide a stylus which will avoid the defects inherent in the resultsobtained by the customary metal needles, particularly the scratchy,metallic sounds and the unpleasant mingling of blaring noises producedby the ordinary needles. To accomplish the improved results of myinvention, I make the talkingmachine stylus of a non-metallic elasticmaterial, .such as lignum-vitae or boxwood or various equivalentsubstances referred to hereinafter.

A specific embodiment of my invention will now be described in detailwith reference to the accompanying drawings, in which Fig. 1 is a sideelevation of a talkingmachine reproducer fitted with my improved needle;Fig. 2 is a side view of such needle; and Fig. 3 is a longitudinalsection of the needle.

and a conoidal enlarged integral head E with a recess or axial socket inwhich the reproducing point as of sapphire F is suitably secured, as byglue G. This stylus E,

is made of an elastic non-metallic material such as bone.

The long shank and the conoidal head provide an elastic stylus which hasthe requisite strength at the head where the point F is secured. The useof non-metallic elas tic material such as bone gives substantially ahalf tone effect, that is to say, eliminates substantially allscratching noises, softens the tone produced and improves its quality,prevents blast and confusion of tones, avoids metallic noises, and isparticularly superior when the instrument is used in a small space,where with the metal needles chiefly employed hitherto screechingmetallic sounds are very unpleasantly prominent.

I claim as my invention:

A half tone stylus for phonographs comprising a bone member having a.relatively EUGENE A. WIDMANN.
